Abstract: 1330899 Separating liquids by distillation PARKSON CORP 20 Nov 1970 [26 Nov 1969] 55371/70 Heading B1D A method of treating a liquid mixture of at least three constituents having different boiling points from each other, when in the mixture, to separate at least the two most volatile of the constituents from the mixture, comprises passing the mixture in turbulent flow through a heated tortuous flow path so that the most volatile constituent is vapourized and superheated, the resulting vapour being carried with the remaining liquid as it continues in turbulent flow through the tortuous flow path so that the vapour mixes intimately with the liquid, and the temperature to which the liquid and the vapour are heated being sufficient for the next most volatile constituent to vapourise at the pressure conditions prevailing in the flow path, whereby the vapour acts as a stripping gas and assists the heat in causing vapourisation of substantially all of the next most volatile constituent, and subsequently removing the two vapourized constituents from the remaining liquid. Mixtures which can thus be separated include a mixture of heptane, hydrocarbon oil and a hydrocarbon resin; and a mixture of water, a low molecular weight polymercaptan, and a high molecular weight polymercaptan. The tortuous flow path may comprise a plate-type evaporator heated by steam, hot water or hot oil.

[Also in Divisions B3 and H1] A semi-conductor wafer 25 is bonded to a surface 17 of a support 10, which surface is flat when cool but convex as shown when hot, by heating the support 10 to the bonding temperature, spreading a bonding agent over the surface 17, placing the wafer 25 into contact with the highest point of the surface 17, e.g. using a rubber-coated vacuum tool, and maintaining the wafer 25 in contact with the surface 17 while the support 10 cools down and resumes its flat shape. The bonding agent is thus forced outwards from the highest point of the surface 17 as the latter cools, and voids in the bonding layer are avoided. After mounting in this way the wafer 25 may be cut into chips for device manufacture. The support 10 is preferably made of a phenolic resin, the bonding agent being glycol phthalate and being preheated and applied in a metered amount to the surface 17. A concave cooled forming tool is used to shape the bonding agent over the surface 17 prior to positioning of the wafer 25.

As shown, an N-type antimony diffused layer 2 is produced on one side of a circular plate 1 of P-type germanium. Radial grooves 3 physically separate eight sectors of layer 2, each sector of the plate being provided with comb-like or radiation transparent ohmic contacts 4, on both opposed surfaces. Alternatively, a P-N junction may be obtained by diffusion of Al on to an N-type Ge plate.

Abstract: 1,245,783. Uses of photochromism. RCA CORPORATION. 5 Dec., 1968 [7 Dec., 1967], No. 57756/68. Heading C4S. A display device comprises a photochromic screen 16, means 15 for selectively concentrating or focusing light at discrete regions within the screen volume to produce in these regions a power intensity to change the light absorbtion characteristic of the regions and means for directing on to the screen light of an intensity which produces no change to provide a three dimensional display. A light beam 12 from a laser 11 is passed through a light intensity modulator 13 and light deflector 14 which produces a two dimensional raster. The beam is then focused by a lens 15 on a transparent p.c. target 16 to provide a 10 micron diameter sphere of light of an intensity which turns the target opaque by double photon absorbtion. The target is moved to form the 3 dimensional pattern which may comprise a series of two dimensional patterns. Data is read by scanning the target with an unfocused beam or flooding the target with light from the laser 11 or another source. The pattern is erased by flooding or scanning the target. The p.c. material may be organic, CaF 2  La or SrTiO 3  : Fe, Mo, the source 11 includes ruby, A, Kr, Xe or Nd doped YAG lasers.
